Abstract

Abstract : Introduction. : When clinicians think about Staphylococcus aureus bacteria, what comes to the mind of most is the dreaded methicillin‐resistant form. However, clinicians should not forget the methicillin‐susceptible type, which is just as virulent. Case presentation. : The authors present the case of a 20‐year‐old woman who was admitted with septic shock and multi‐organ failure and was found to have disseminated methicillin‐susceptible Staphylococcus aureus (MSSA) infection. The patient had persistent blood cultures positive for MSSA. A transesophageal echocardiogram showed a 1.1 cm vegetation in the mitral valve, and the patient had bilateral pleural effusions that grew MSSA. An MRI of the brain showed multiple areas consistent with infarctions thought to be secondary to septic emboli. The patient underwent a mitral valve replacement and was treated with a prolonged course of parenteral nafcillin. Discussion. : This case illustrates a severe clinical presentation and management of MSSA infections.
